the purpose of this study was to determine the effect of interval sprint exercise and a detraining period on lipid peroxidation (mda) and the response of antioxidant system (frap, uric acid, bilirubin and total protein). for this purpose, 35 male rats were divided randomly into two groups: sprint group (experimental) (n=20) and control group (n=15, without any training). experimental group trai...

The aim of this study was to determine the antioxidant potential of the serum and the level of lipid oxidation products in the sera of apparently healthy adult males. The "antioxidant power" of the serum, defined as the ability to reduce ferric ions by antioxidants from the serum (FRAP), was taken as the indicator of total antioxidation potential. The formation of lipid oxidation products was e...

Objective(s) Crocin bleaching assay (CBA) is a new method for determination of antioxidant capacity. In CBA, addition of hydrogen to the conjugated double bonds of crocin results in reduction of crocin and increase in the absorbance at 440 nm, which is considered as a measure of antioxidant potential. Here CBA method was set up using di-gentiobiosyl crocin or a-crocin from Iranian saffron. The...

A simple, automated test measuring the ferric reducing ability of plasma, the FRAP assay, is presented as a novel method for assessing "antioxidant power." Ferric to ferrous ion reduction at low pH causes a colored ferrous-tripyridyltriazine complex to form. FRAP values are obtained by comparing the absorbance change at 593 nm in test reaction mixtures with those containing ferrous ions in know...

OBJECTIVE To explore the hepatoprotective and anti-oxidant activities of the methanolic leaf extract of Bridelia micrantha (B. micrantha) on paracetamol induced liver damage in Wistar rats. METHODS Parameters were measured including alanine aminotransaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin and total protein. The anti-oxidant effects were studied ...

The aim of the work was to assess the influence of some non-enzymatic antioxidants (uric acid, blood urea, bilirubin) on the antioxidant status of rat’s organism during the experimental acute haemorrhagic necrotising pancreatitis. The experiment was carried out on male Wistar rats, body weight 280-320 g, which were divided randomly into control and experimental groups. The control group (n=8) u...

There are no published studies examining the effects of N-acetylcysteine (NAC) administration on the non-enzymatic defence systems in humans exposed to lead. In view of this, it was decided to measure the levels of uric acid (UA), albumin, bilirubin and alpha-tocopherol before and after treatment with NAC. An estimation was also made of the degree of oxidative stress by measuring the ferric red...

background: transcutaneous bilirubinometry (tcb) is a simple method for estimating bilirubin levels in neonates. this method is noninvasive, quick, and painless. we aimed to compare serum and cutaneous bilirubin measurements in term neonates.method: in this descriptive cross-sectional study, 200 neonates with icter with birth weights of at least 2500 grams were studied. tcb was measured using a...
